SEAT-SPRING FOR BICYCLES.

SPECIFICATION forming part of Letters Application filed January 27, 1882. (No model.)

To all whom it may concern Be it known that I, Josnrn WHITE, of Goventry,inthe countyof Warwick, England, have invented an Improvement in Seat-Springs for Bicycles, of which the following is a specification.

Springs for vehicles have been made with rubber cylinders within cases at the ends of has been made with suspending-rods at the ends, around which sections of tubular rubber which the seat-spring is suspended, have been employed; but such rubber springs are either too rigid for the support of the seat, or liable to break when used as suspending-loops. Bi cycle seat-springs must be sufliciently strong to support the rider, and at the same time the bearings for the ends of the springs should yield and prevent the disagreeable concussion resulting from riding over stone pavements.

My invention is intended for availing of the yielding character of rubber for the bearings at the ends of the seat-springs without any risk of injury to the rubber, and without any projecting rods or nuts to catch in the hand or clothing in mounting or dismounting.

In the drawings, Figure 1 is a side View of the seat-spring and a portion of the backbone of the bicycle. Fig. 2 is a plan of the same. Fig. 3 is a cross-section of the spring front rubbers and support, and Fig. 4 is a cross-section of the spring back rubber and support.

Patent No. 258,333, dated May 23, 1882,

Patented in England February 7, 1881, No. 512.

The spring a is adapted to receive the saddle b, the same being connected by clip-bolts in any usual manner. At the end next to the head of the machine the spring a is forked and coiled up into cylindrical forms for the reception of the rubber cylinders 00, and through these rubbers there are holes for the joint-pin d, that passes through the forward or solid. end of the spine of the bicycle, At the other end the spring a is forkedand terminates with two eyes for the bolt 0 to pass through. This bolt goes through the rubbercylinderf, that is within the cylinder g, that is bolted to the backbone, or otherwise attached. The weight upon the seatspring is supported at the ends upon the rubber cylinders c 0 and. f, and the bolts or joint-pins d c act to displace the rubber and allow such pins to move slightly, and thereby the jar that would reach the rider is lessened by the yield of the rubber.

I claim as my invention-- The combination, with the seat, seat-spring, and backbone in a bicycle, of the rubber cylinders c 0 and f, the cylindrical cases for such springs, thejoint pins or bolts passing through such rubber cylinders, and the jaw connected with the spine, substantially as set forth.

Signed by me this 15th day of November,

JOSEPH WHITE. Witnesses:
